HARROW, AND MARKER.

SPECIFICATION forming part of Letters latent No. 420,336, dated January28 1890.

Application filed March 23, 1889.

To aZZ whom it may concern:

Be it known that I, HENDERSON J CRooKnR, J r., a citizen of the UnitedStates, residing at Orlinda, in the county of Robertson and State ofTennessee, have invented new and useful Improvements in a Combin edCultivator, H arrow, and Marker, of which the following is aspecification.

My invention relates to cultivator-barrows, or that class of harrows inwhich adjustable cultivator shovels or plows are connected with thebarrow-frame.

It is the purpose of said invention to provide simple and readily-adjustable means for setting or removing any one or more of thecultivator-plows, either as regards the depth of working or the intervalbetween the furrows, and to combine the same in a convenient and compactmanner with the frame of the harrow.

It is my further purpose to combine with said harrow and plows ahand-marker which may be used upon either side of the same at pleasure,and which is capable of adjustment upon its support to render theintervals between the furrow-marks, or rows of planting, greater orless, as may be desired.

It is my purpose, finally, to provide a har row of this class with arocking-tongue connection or bar carrying the central tooth of theharrow to enable the draft-animals to pass over inequalities in theground without disturbing the horizontal movement of the harrow.

The invention consists in the several novel features of construction andnew combinations of parts hereinafter fully set forth, and then pointedout in the claims following this specification.

Referring to the accompanying drawings, Figure 1 is a plan viewillustrating my invention. Fig. 2 is a side elevation of the parts shownin Fig. 1. Fig. 3 is a rear elevation of the same. Fig. 4 is a detailview of one of the cultivator-shovels and its supports detached.

In the said drawings, the referencemumeral 1 denotes the A-frame of thebarrow, having any suitable construction and provided with the usualtransverse brace 2, which I prefer to re-enforce by a centrallongitudinal brace Serial No. 304,401. (No model.)

3, which is connected to a buttress at and meets the cross-brace 2centrally. Between the converging side bars 1 of the A-frame, at theirapex or forward end,.is mounted a tonguebeam 5, lying between theinterior beveled and parallel faces of the side bars, to which it ispivotally connected by a horizontal bolt 6, whereby the tongue-beam ispermitted to swing upward to any required angle. Upon said beam ismounted a suitable connection 7 for the doubletree, and projecting fromthe lower face of the tongue-beam is a tooth 8, which is the centraltooth of the harrowframe. Upon the transverse brace 2, upon each side ofthe central longitudinal brace 3, is mounted a metallic loop 9,embracing three sides of said crossbrace, its rearwardly-proj ectingends lyingin avertical slot 10, formed in a stock or plate 12 and holdit firmly in place against the brace. The lower end of each stock orplate is bent rearwardly and then downward and a cultivator-shovel 14,of any suitable form, is mounted thereon in any suitable manner, aconvenient fastening being a bolt or nut. Upon the central longitudinalbrace 3 is mounted a metallic supportiu gplate 15, crossing thetransverse brace and projecting in rear thereof. At a suitable point inthe rear the end of the plate is turned upward at a proper angle,forming an inclined support 16, from which bolts 17 project rearwardly.These bolts pass througha vertical slot 18, formed in a stock or plate19, and receive. nuts 20, which clamp the stock closely against thesupport 16 and hold it firmly in place. A cultivatorshovel 20 is mountedon the stock 20 in any suitable manner. Upon the horizontal end of theplate 15 is lapped and bolted a bracket 21, having an eye 22, whichsurrounds the upwardly-bent support 16, as well as the stock 19, thebracket being extended to the rear sufficiently to form a point ofpivotal attachment for an arm 23, which projects over the side bar ofthe harrow, to which it is detachably secured by a hook or keeper 24C,in which it is held by a pin or peg 25, set in a hole in the bar. Theprojecting end of the arm is provided with a series of openings 26, inany one of which is placed the end of a drop-bar 27, fastened by nuts28, turned thereon upon each side of the arml The lower end of thedrop-bar c'arries a land-marking wheel or other device 29, suitable formarking the furrow and preserv- 'ing the intervals between furrows.

By means of the construction described I am able to adjust thecultivator-shovels 14: laterally and vertically and to impart a similarvertical adjustment to the central cultivator 20. I may also operate theland-marker upon either side of the frame and at any desired adjustment,thus harrowing the ground and laying it ofi at the same time that thesucceding furrow is marked or its position indicated.

The invention is well adapted to corn and tobacco crops, as will readilybe' seen, and the plows maybe used upon any land containing smallvegetation of any kind, the harrow being used simultaneously.

The harrow is guided by handles 30, mount ediup'on the frame in anysuitable manner.

It will readily be understood that the central low or cultivator isexceedingly useful in laying ofi the ground at the same time that it isharrowed.

What I claim as my invention is- 1. A cultivator consisting of theconverging side bars having pendent teeth, abuttress 4 between the sidebars, adjacent to their junction, a cross-brace connecting the side barsand having slotted shovel carrying stocks clamped to and verticallyadjustable on the cross-brace, and a center brace hailing its endsabutting, respectively, the buttress and the shovel-carryingcross-brace, substantially as described.

2. A cultivator consisting of the converging side bars having pendentteeth, a buttress adjacent to the junction of said bars, acrossbracecarrying vertically-adjustable shovels and connecting the side bars, acenter brace abutting, respectively, the buttress and theshovel-carrying brace, a metallic plate secured to the center brace andextending in rear of the shovel-carrying brace and provided at its rearend with a bracket, a shovelc arrying standard secured to therearwardlyextending plate, and a reversible arm detachably engaging thebracket on said plate, resting on one of the converging arms andcarrying a marker at its outer end, substantially as described. c

In testimony whereof I have affixed my signature in presence of twowitnesses.
